Believability is an important characteristic of intelligent virtual agents, however, very few attempts have been made to define and formalise it. This paper provides a formal analysis of believability, focused on diverse aspects of believability of the agents and the virtual environment they populate, approaching the problem from the perspective of the relationship between the agents and the environment. The paper also presents a computational believability framework built around this

As a proof of concept we have developed a case study, a prototype of an ancient Sumerian city (Uruk), where believable virtual agents simulate the daily life of its citizens. 4 A video showing awareness believability aspects of our framework can be found at:
